RGB Color LED Display Modules of the new technology
 For notebook computers or desktop RGB Color LED Display Modules needs to be used in more complex color display, but also have to deal with color display color filter layer. Typically, in a color RGB Color LED Display Modules panel, each pixel is made up of three liquid crystal cells, each of which has a red, green, or blue filter in front of each cell. In this way, through different cells of the light can be displayed on the screen different colors.
RGB Color LED Display Modules to overcome the CRT bulky, power consumption and flashing shortcomings, but also brought the cost is too high, the angle is not wide and color display is not ideal and so on. CRT display can choose a series of resolutions, and can be adjusted according to the screen requirements, but the RGB Color LED Display Modules screen contains only a fixed number of LCD units, only in the full screen using a resolution display (each unit is a pixel ).
CRT usually has three electron guns, the injection of electronic flow must be accurately gathered, otherwise it will not get a clear image display. But the RGB Color LED Display Modules does not focus on the problem, because each LCD unit is a separate switch. This is exactly why a picture is so clear on the RGB Color LED Display Modules screen. RGB Color LED Display Modules also do not have to care about the refresh rate and flicker, the LCD unit is either open or off, so the image displayed at a low refresh rate of 40 to 60 Hz does not flicker than the image displayed at 75 Hz. However, RGB Color LED Display Modules screen LCD unit will be prone to flaws. For 1024 × 768 screens, each pixel consists of three units, each responsible for red, green and blue display, so a total of about 2.4 million units (1024 × 768 × 3 = 2359296). It is difficult to ensure that all of these units are intact. Most likely, some of them have been short-circuited ("bright spots"), or broken ("black spots"). So that is not so high that the product does not appear flawed.
RGB Color LED Display Modules display contains some of the CRT technology has not been used. The light source for the screen is the fluorescent tube that wraps around it. Sometimes, you will find a part of the screen appears unusually bright lines. There may also be some indecent stripes, a special light or dark image will affect the adjacent display area. In addition, some fairly sophisticated patterns (such as dithered images) may appear ugly ripples or disturbances on the LCD screen.
Now, almost all of the RGB Color LED Display Modules used in notebook or desktop systems use thin film transistors (TFTs) to activate cells in the liquid crystal layer. TFT RGB Color LED Display Modules technology can display more clear, bright images. Although the early RGB Color LED Display Modules is a non-active light emitting device, the speed is low, the efficiency is poor, the contrast is small, although it can display clear text, but in the fast display of images often produce shadows, affecting the video display, Applies only to handheld computers, pagers, or mobile phones that require black and white display.
With the ever-changing technology, RGB Color LED Display Modules technology is also evolving. At present, the major RGB Color LED Display Modules manufacturers have increased the RGB Color LED Display Modules R & D costs, and strive to break through the RGB Color LED Display Modules technology bottlenecks to further accelerate the RGB Color LED Display Modules of the industrialization process, reduce production costs, To achieve the user can accept the price level.
